In reviewing a patient’s complete blood count (CBC) results, the nurse notes a "shift to the left." What is the significance of these results?

There is an elevated number of immature thrombocytes.

There is an elevated number of immature neutrophils (bands),

There is an elevated number of mature neutrophils (segs)

There is an elevated number of mature erythrocytes

Answer and Explanation

The Correct Answer is B

A. There is an elevated number of immature thrombocytes - Thrombocytes are platelets, and a shift to the left does not refer to these.

B. There is an elevated number of immature neutrophils (bands) - A "shift to the left" typically refers to an increase in immature neutrophils, also known as bands, in the blood. This often indicates an acute infection or inflammation as the body is producing and releasing more neutrophils to fight an infection.

C. There is an elevated number of mature neutrophils (segs) - An elevated number of mature neutrophils (segmented neutrophils) does not indicate a shift to the left. The term specifically refers to immature forms.

D. There is an elevated number of mature erythrocytes - Mature erythrocytes are red blood cells, and a shift to the left does not pertain to red blood cell counts or maturity.

Correct Answer is D

Explanation

A. Slurred speech - This is not a common symptom of iron deficiency anemia. It might suggest a neurological issue or other condition.

B. Confusion - While severe anemia might lead to confusion due to reduced oxygen delivery to the brain, it is not as common as fatigue and is usually seen in more advanced stages or in combination with other factors.

C. Pain - Pain is not a typical symptom of iron deficiency anemia unless it is related to other conditions like muscle fatigue from overall weakness.

D. Fatigue - Fatigue is a hallmark symptom of iron deficiency anemia due to the decreased ability of the blood to carry oxygen to tissues, leading to overall tiredness and lack of energy.

A. Avoid crowds B. Eat plenty of fresh fruits and vegetables C. Take temperature weekly. D. Perform mild exercise, such as gardening

Correct Answer is A

Explanation

A. Avoid crowds - Neutropenic patients are highly susceptible to infections. Crowded places increase the risk of exposure to pathogens.

B. Eat plenty of fresh fruits and vegetables - While generally healthy, fresh fruits and vegetables can harbor bacteria, posing a risk for infection in neutropenic individuals. Cooked or properly washed and peeled produce is safer.

C. Take temperature weekly - Neutropenic patients should monitor their temperature daily, not weekly, to detect infections early.

D. Perform mild exercise, such as gardening - Gardening can expose individuals to soil-borne organisms that could lead to infections. Indoor exercises or those that don’t involve potential pathogen exposure are safer.
